In this thesis, the effect pressure on the synthesis and purification of high purity ethylbenzene was analyzed using COCO V.3.3 software. For this study, two fixed conversion reactors were used with a conversion of 73,5% mol of ethylene to ethylbenzene and ethylene to diethylbenzene of 25,5%; at the pressure of 2,3 atm in the first reactor and a conversion of 22,13 mol% of diethylbenzene to ethylbenzene, and of ethylene to ethylbenzene of 97% at the pressure of 2,1 atm in the second reactor. For the separation of the resulting mixture, Chemsep CAPE OPEN configured two distillation columns in series. Both columns used the Chao Seader model for the activity coefficient calculation and for the phase equilibrium; and enthalpies of excess for energy balances. The first of twenty step at 0,3 atm and with reflux ratio of 2,512; allowed to obtain a distillate with 99,88% mol of benzene mol with a heat consumption in the boiler of 4,4 MW and a bottom product with 69,07% mol of ethylbenzene. The second column of twenty-four steps at 0,1 atm and with a reflux ratio of 0,432; allowed the recovery of ethylbenzene in the distillate with a purity of 99.9% mol and diethylbenzene with 99.9% mol as the bottom product, with a heat consumption of 7,83 MW. The best-feed location to the first column was the tenth step, and for the second the fifteenth avo step. From these values, the reflux ratio increases significantly. The heat consumption in the boiler of the second column was greater by 3.43 MW compared to the first
